Optionally, there are multiple scraping assemblies, and the feed channel 1 is also provided with multiple groups, so as to facilitate the hair removal work of multiple carrier tapes at the same time and improve the working efficiency.

[0036] Specifically, Fig. 9 As shown, in this embodiment, by providing blades 11 on both sides of the carrier tape, the hair on both sides of the carrier tape can be cut off and scraped off when the carrier tape passes through.

[0037] The carrier tape inlet guide mechanism of this embodiment is used to limit the movement of the carrier tape, so that the carrier tape can move accurately and ensure the effect of scraping off the hair. Figures 6 to 8 As shown, the carrier inlet guide mechanism includes a guide block 2 and a guide cover plate 3, a feed channel 1 is formed between the guide block 2 and the guide cover plate 3, the guide block 2 is provided with a "convex" shaped through groove 4, the guide cover plate 3 is provided with a protrusion 5, after the guide cover plate 3 is installed on the guide block 2, the protrusion 5 is located in the through groove 4 and the feed channel 1 is formed between the protrusion 5 and the through groove 4.

[0038] Specifically, a plurality of square protrusions 5 are provided on the side of the guide cover plate 3 that contacts the guide block 2. When assembled, the protrusions 5 cover the through slots 4 of the guide block 2 to form a Figure 6 The feeding channel 1 is also shaped like a "convex" character. After the carrier enters the feeding channel 1, Figure 2 As shown, the carrier belt can be limited so that the carrier belt maintains a predetermined route during movement, and the carrier belt can be reduced from swinging left and right or up and down in front of the deburring knife block 8. In actual use, the corresponding guide block 2 and guide cover plate 3 can be replaced according to the size of the carrier belt. Furthermore, screw holes are provided at both ends of the guide block 2 and the guide cover plate 3, which can be fixed to the front end of the base 25 by screws. The feed end of the guide block 2 is provided with a rounded corner structure 6, and the square protrusion 5 of the guide cover plate 3 is provided with a slope 7, which is located at the feed end. The rounded corners of the guide block 2 and the slope 7 of the guide cover plate 3 form a feed bell mouth, which can guide the carrier belt to be quickly inserted into the feed channel 1, thereby improving work efficiency.

[0039] The hair removal mechanism of this embodiment is as follows: Figure 2 , Figure 3 , Figures 9 to 13 As shown, it includes a deburring knife block 8, a spacing adjustment member and a knife block pressing plate 13. In this embodiment, the spacing adjustment member is preferably a spring 12, and the deburring knife block 8 is provided with a countersunk hole 17. The two ends of the spring 12 are respectively assembled in the countersunk holes 17 of the two deburring knife blocks 8, thereby fixing the spring 12 and preventing the spring 12 from falling off during use.

[0040] Specifically, the hair removal blade block 8 is provided with Fig. 9 The fine slot 9 shown in the figure sets two hair removal blades 8 facing each other, that is, the two slots 9 are set facing each other to form a passage 10 for the carrier tape to pass through, and the end of the slot 9 is provided with a knife edge 11, the angle of the knife edge 11 is less than 90 degrees, which is an acute angle, so that the hair at both ends of the carrier tape can be removed more effectively. A spring 12 is set between the two hair removal blades 8, such as Figure 3 , Fig.12 and Fig.13As shown, the spring 12 can be optionally located between the two scraping components, that is, the countersunk hole of the dehairing blade block 8 is set on the side where the slot 9 is not set. Therefore, the dehairing blade block 8 can be pressed against the elasticity of the spring 12, that is, a structure in which adjacent scraping components press against each other is formed, so that the side of the dehairing blade block 8 provided with the slot 9 can stably contact the carrier tape, ensuring effective scraping of the hair; when the size of the carrier tape entering the aisle 10 increases, the distance between the two dehairing blade blocks 8 is increased by squeezing the spring 12, so that the size of the aisle 10 adapts to the new carrier tape size, which is convenient for adjusting the size of the aisle 10 and has high applicability. Therefore, as another implementation of this embodiment, the spacing adjustment member can be other elastic structural components other than the spring 12, and this embodiment is not limited thereto, or a connecting rod is set, the two ends of the connecting rod are located in the two countersunk holes 17, and the spring 12 is set between the connecting rod and the hole wall of the countersunk hole 17, which can also achieve the effect of spacing adjustment, and the connecting rod can also ensure that the two dehairing blade blocks 8 maintain balance.

[0041] Furthermore, the dehairing blade block 8 is provided with a square opening 14, the blade block pressure plate 13 includes a main pressure rod 15 and a plurality of side pressure rods 16, the plurality of side pressure rods 16 are arranged at intervals on the main pressure rod 15, and a side pressure rod 16 corresponds to a scraping assembly, and a spacing is provided between the two dehairing blade blocks 8 of the scraping assembly, and the spacing is provided in accordance with the size of the carrier tape, and the openings 14 of the plurality of dehairing blade blocks 8 are arranged in a row, so the main pressure rod 15 is embedded in the openings 14 of all the dehairing blade blocks 8, and the side pressure rod 16 is located between the two dehairing blade blocks 8 of the scraping assembly, as shown in FIG. Figure 2 As shown, there are two deburring knife blocks 8 facing back to back between adjacent side pressure rods 16, and a spring 12 is arranged between the two deburring knife blocks 8, so a certain position adjustment space is arranged between the two deburring knife blocks 8, and the side of the deburring knife block 8 where the groove is arranged abuts against the side pressure rod 16. At this time, the size of the aisle 10 is the minimum size of the carrier tape. When the width of the carrier tape increases, the width of the aisle 10 also increases, so that the size of the aisle is adjusted by squeezing the spring 12, and the position adjustment space set between the two deburring knife blocks 8 is reduced, and the side of the deburring knife block 8 where the groove is arranged does not conflict with the side pressure rod 16. If the width of the carrier tape continues to increase, the action principle of the deburring knife block 8 and the spring 12 continues to act as in the above process. Therefore, in actual use, the adjustable space of the aisle can be changed by changing the size of the side pressure plate 16. Furthermore, both ends of the knife block pressure plate 13 are also equipped with pressure plate positioning seats 18, and the pressure plate positioning seats 18 are provided with screw holes, such as Figure 2 , Figure 3As shown, all the dehairing blades 8 and the blade block pressing plate 13 are restricted between the two pressing plate positioning seats 18, and then the pressing plate positioning seat 18 is locked with the base 25, and the blade block pressing plate 13 is locked with the pressing plate positioning seat 18, so that the dehairing work of the carrier tape can be smoothly carried out, and the influence of the structural device on the accuracy of the carrier tape operation can be reduced. In actual use, if the size of the carrier tape is changed, the size of the blade block pressing plate 13 can be changed according to actual needs to adapt it to the spacing of the new dehairing blades 8, and this embodiment does not make specific restrictions.

[0042] The blowing mechanism includes a blowing pipe 19, a blowing connection block 20 and an air inlet pipe 21.

Specifically, Figure 2 , Figure 3 , Fig.14 and Fig.15 As shown, the air inlet pipe 21 is connected to an external air outlet device, and the air blowing pipe 19 is connected through the air inlet pipe 21, and then air is blown to the carrier tape through the air outlet 22 of the air blowing pipe 19 to blow away excess hair and keep the carrier tape clean.

[0043] like Figure 3 , Figure 5 and Fig.16 As shown, the hair collection mechanism includes a recovery bucket 23 and a vacuum suction pipe 24. The recovery bucket 23 is located below the carrier belt. One end of the vacuum suction pipe 24 is connected to the recovery bucket 23, and the other end of the vacuum suction pipe 24 is connected to an external vacuum device.

[0044] Specifically, the recovery bucket 23 is installed below the carrier belt to receive the hair blown off by the blowing mechanism. Further, the hair is sucked by the vacuum suction pipe 24 to ensure that the hair can enter the recovery bucket 23, thereby reducing the possibility of hair scattering.
